Microprocessor13. If you do not intend to install a microprocessor in the socket, install the socketdust cover that you removed in step 2 on page 224 on the socket.Attention: The pins on the socket are fragile. Any damage to the pins mayrequire replacing the system board.14. If you are instructed to return the microprocessor, follow all packaginginstructions, and use any packaging materials for shipping that are supplied toyou.Installing a microprocessor and heat sinkFor information about the type of microprocessor that the server supports and otherinformation that you must consider when you install a microprocessor, see theInstallation and User’s Guide on the IBM Documentation CD.Read the documentation that comes with the microprocessor to determine whetheryou must update the IBM System x Server Firmware.Important: Some cluster solutions require specific code levels or coordinated codeupdates. If the device is part of a cluster solution, verify that the latest level of codeis supported for the cluster solution before you update the code.To download the most current level of server firmware, complete the following steps:1. Go to http://www.ibm.com/systems/support/.2. Under Product support, click System x.3. Under Popular links, click Software and device drivers.4. Click System x3630 M3 to display the matrix of downloadable files for theserver.Important:v Microprocessors are to be installed only by trained service technicians.v Always use the microprocessor installation tool to install a microprocessor. Failingto use the microprocessor installation tool may damage the microprocessorsockets on the system board. Any damage to the microprocessor sockets mayrequire replacing the system board.v A startup (boot) microprocessor must always be installed in microprocessorconnector 1 on the system board.v To ensure correct server operation, make sure that you use microprocessors thatare compatible and you have installed an additional DIMM for microprocessor 2.Compatible microprocessors must have the same QuickPath Interconnect (QPI)link speed, integrated memory controller frequency, core frequency, powersegment, cache size, and type.Chapter 5.
